"Any chance this can be developed for commercial aircraft."
Probably not. This article http://www.americanheritage.com/articles/magazine/it/2006/4/2006_4_26.shtml
lists a US carrier catapult takeoff as roughly 160mph in 2.5secs. That's about 29ms^-2 or close to 3g. while a lot of people could take 3g for less than 3 secs (modern roller coaster rides can give this, and I imagine some do quite a bit more) it would still likely kill a proportion. And energy requirements scale with mass. The aircraft in the article is 78oooLb (c35 000 Kg). An Airbus would be 10 to 20x that.
Basically everywhere else other than at sea building a longer runway is a *lot* cheaper and simpler.
OTOH if you wanted a singel stage to orbit vehicle that could land *and* take off horizontally (looked at by the USAF in the early 90s to the point where Boeing were prepared to offer it as a *fixed* price contract) this would be a very good choice.
